I have a 94 Intruder 1400 that I purchased from my father in law last year. He bought it new and it had 7,000 miles on it when I got it. I like it very much ,but it only has 4 gears. I noticed on this site the specifications say 5 speed. I inquired at the local Suzuki dealer and they said it should have an overdrive? My father in law said that it just has four gears. If this is the case, how difficult would it be to add a fifth gear? Any help would be appreciated.
